ZmnSCPxj jxPCSnmZ 67590fc6be lightningd/invoice.c: Add timeout parameter to waitanyinvoice.
Fixes: #3192

Changelog-Added: `waitanyinvoice` now supports a `timeout` parameter, which when set will cause the command to fail when the timeout is reached; can set this to 0 to fail immediately if no new invoice has been paid yet.

.SH NAME
lightning-waitanyinvoice - Command for waiting for payments
.SH SYNOPSIS
\fBwaitanyinvoice\fR [\fIlastpay_index\fR] [\fItimeout\fR]
.SH DESCRIPTION
The \fBwaitanyinvoice\fR RPC command waits until an invoice is paid, then
returns a single entry as per \fBlistinvoice\fR\. It will not return for
any invoices paid prior to or including the \fIlastpay_index\fR\.
This is usually called iteratively: once with no arguments, then
repeatedly with the returned \fIpay_index\fR entry\. This ensures that no
paid invoice is missed\.
The \fIpay_index\fR is a monotonically-increasing number assigned to an
invoice when it gets paid\. The first valid \fIpay_index\fR is 1; specifying
\fIlastpay_index\fR of 0 equivalent to not specifying a \fIlastpay_index\fR\.
Negative \fIlastpay_index\fR is invalid\.
If \fItimeout\fR is specified, wait at most that number of seconds, which
must be an integer\.
If the specified \fItimeout\fR is reached, this command will return with an
error\.
You can specify this to 0 so that \fBwaitanyinvoice\fR will return
immediately with an error if no pending invoice is available yet\.
If unspecified, this command will wait indefinitely\.
.SH RETURN VALUE
On success, an invoice description will be returned as per
\fBlightning-listinvoice\fR(7): \fIcomplete\fR will always be \fItrue\fR\.
Possible errors are:
.RS
.IP \[bu]
904\.
The \fItimeout\fR was reached without an invoice being paid\.
